Diseño y simulación del control basado en algebra lineal aplicado en los conversores usados en el manejo de energía de un sistema híbrido de potencia compuesto por un arreglo de paneles fotovoltaicos y baterías.

Abstract

This document presents a simulation of a hybrid power system composed of photovoltaic panels and batteries, whose main focus will be to evaluate the linear algebra based control or LABC on power electronic circuits. To do so, an array of different DC-DC converter topologies is proposed to handle various system parameters:

• The power supplied by the PV panels using MPPT (Maximum Power Point Tracking) and PPT (Power Point Tracking) algorithms. • The power flow on the batteries and battery charging using the CC (Constant Current) technique. • Power flow supplied to the load. • Voltage over the DC bus.

On the following sections, the elements that compose the system will be dimensioned, the power levels that it will handle will be delimited, the converter controllers will be designed, and the results will be validated under different load profiles, irradiances, temperatures, and disturbances in the DC bus. To evaluate the performance of the LABC control, its operation was compared with conventional PI controllers, to determine the feasibility, advantages, and disadvantages of LABC control applied in power systems.
